+pomfland has notified me that:
+
+palemoon could potentially be using some
+libraries belonging to seamonkey-solibs. A launcher script might be
+necessary:
+
+> export LD_LIBRARY_PATH=/opt/palemoon:/opt/palemoon/plugins
+> /opt/palemoon/palemoon "$@"
+
+I will look into this when I get a chance, since it seems non-critical.
